Your first skill in 5 minutes

1. Scaffold a new skill

Run chain new my-skill to create the folder and template file.

Open ~/chain-hub/skills/my-skill/SKILL.md in your editor. The template already includes a name and placeholder description.

Edit the description field (when to use this skill) and the body (what to do). Keep it focused and under 200 lines.

4. Validate

Check frontmatter and structure before you rely on the skill in an editor.

5. Use it in your editor

Mention the skill by name or describe the scenario it covers. The AI picks it up from the linked directory.
